PLASTER MATERIAL, PLASTER AND PLASTER PANEL
PROBLEM TO BE SOLVED: To provide a plaster material that can form plaster having high strength and toughness and reduced in weight.SOLUTION: The plaster material includes quick lime and/or slaked lime, a fine aggregate and a bamboo powder and preferably further includes an aqueous solution with a high Ca ion content as water for kneading the plaster material. The aqueous solution with a high Ca ion content uses one prepared by dissolving quick lime and/or slaked lime in an amount of 2 to 20 g/L on a Ca basis in an acidic aqueous solution; the fine aggregate is lime sand; the acidic aqueous solution is an acetic acid aqueous solution; and the quick lime and/or slaked lime is preferably one produced by firing oyster shells at 900 to 1,200°C.SELECTED DRAWING: Figure 1
【課題】高い強度及び靱性を有すると共に軽量化された漆喰を形成可能な漆喰材料を提供する。【解決手段】生石灰及び／又は消石灰と細骨材と竹粉末とを含み、更に漆喰材料を混練する水として高Ｃａイオン含有水溶液を含むことが好ましい漆喰材料。前記高Ｃａイオン含有水溶液は、生石灰及び／又は消石灰を酸性水溶液にＣａベースで２〜２０ｇ／Ｌ溶解させたものを使用し、前記細骨材には、石灰製砂であり、酸性水溶液が酢酸水溶液であり、生石灰及び／又は消石灰は、カキ殻を９００〜１２００℃で焼成したものが好ましく、漆喰材料。【選択図】図１
